Detachable sight with momentary switch of light with control logic

ABSTRACT

In one aspect, a sight with a momentary switch to control a laser beam on the sight may include a momentary sensor, a plurality of locking screw to lock the sight onto a firearm, a laser sight, a push button switch, a charging socket, and a laser adjustment screw. When in use, the user can press the push button switch to turn on the sight. In one embodiment, the momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam will be turned off. So, if the user wants to turn off the laser beam, the user can simply move the finger toward the momentary sensor to somewhat covers the momentary sensor to deflect the infrared light emitting therein.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 (e) to U.S.Provisional Patent Application Ser. No. 62/827,732, filed on Apr. 1,2019, the entire contents of which are hereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to a detachable sight and moreparticularly to a detachable sight with control logic of the lightthereon.

BACKGROUND OF THE INVENTION

Laser sights are particularly effective as sighting devices because thelasers illuminate spots on their targets and do not require users toalign an eye with a sighting device, which can limit or obscure theuser's view of the targets or their surroundings. When mounted onfirearms, the laser sights emit beams that are directed along theexpected flight paths of projectiles discharged from the firearms.Usually the laser beam is triggered to turn on when the user pushes ortouches the on button. In the present invention, with a differentcontrol logic, the laser beam can be triggered to “turn off” when theuser touches the sensor on the sight.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a detachable sightwith a switch with a momentary sensor for a firearm.

It is another object of the present invention to provide a detachablesight with a momentary sensor that can be used to shut off the laserbeam of the sight when the user's finger blocks the momentary sensor.

In one aspect, a sight with a switch to control a laser beam thereon mayinclude a main body, a switch with a momentary sensor, a laser sight, aplurality of locking screws to lock the sight onto a firearm, a laseradjustment screw, and a charging socket. In one embodiment, the laser ofthe laser sight is tactical low-profile compact W/E adjustable greenlaser. In another embodiment, the mode of the sight is switchable fromconstant to pulse, and vice versa. In another embodiment, the switch canbe pushed to be ON or OFF. It is important to note that a furtherembodiment, the momentary sensor can be easily controlled especially forsilent and quick operation. In still a further embodiment, the chargingsocket has a built-in rechargeable battery compatible with USB Type-Ccharger.

The sight can be attached to a firearm. The user can first loosen thelocking screws of the sight, push/hold the locking screws, align thelocking screws with the groove of the rail of the firearm, clamp thesight onto the rail of the firearm, and tighten the locking screw tocomplete the mounting process.

When in use, the user can press the switch to turn on the sight. In oneembodiment, the momentary sensor can emit infrared light and if theinfrared light is deflected, the laser beam emitted from the laser sightwill be turned off. So, if the user wants to turn off the laser beam,the user can simply move the finger toward the momentary sensor tosomewhat covers the momentary sensor to deflect the infrared lightemitting therefrom. In one use case, when the firearm with the sight isdisposed into a gun bag, the momentary sensor can still be triggered toturn off the laser beam.

It is noted that the momentary sensor is configured to temporarily shutoff the laser beam. Namely, when the user moves the finger away from themomentary sensor, the infrared light emitting therefrom is not deflectedand the laser beam from the laser sight can again be turned on. It isalso noted that the switch has to be “ON” to trigger the momentarysensor.

In a further embodiment, the sight can be charged through the chargingsocket. More specifically, one end of a USB charging cable can beplugged into the charging socket on the sight and the other end can beconnected to a USB power adapter to complete the charging process.

DETAILED DESCRIPTION OF THE INVENTION

The detailed description set forth below is intended as a description ofthe presently exemplary device provided in accordance with aspects ofthe present invention and is not intended to represent the only forms inwhich the present invention may be prepared or utilized. It is to beunderstood, rather, that the same or equivalent functions and componentsmay be accomplished by different embodiments that are also intended tobe encompassed within the spirit and scope of the invention.

Unless defined otherwise, all technical and scientific terms used hereinhave the same meaning as commonly understood to one of ordinary skill inthe art to which this invention belongs. Although any methods, devicesand materials similar or equivalent to those described can be used inthe practice or testing of the invention, the exemplary methods, devicesand materials are now described.

All publications mentioned are incorporated by reference for the purposeof describing and disclosing, for example, the designs and methodologiesthat are described in the publications that might be used in connectionwith the presently described invention. The publications listed ordiscussed above, below and throughout the text are provided solely fortheir disclosure prior to the filing date of the present application.Nothing herein is to be construed as an admission that the inventors arenot entitled to antedate such disclosure by virtue of prior invention.

In one aspect, as shown in FIGS. 1 and 2, a sight 100 with a switch tocontrol a laser beam thereon may include a main body 110, a switch 120with a momentary sensor 121, a laser sight 130 emitting laser beamscontrolled by the momentary sensor 121, a plurality of locking screws140 to lock the sight onto a firearm, a laser adjustment screw 150, anda charging socket 160. In one embodiment, the laser of the laser sight130 is tactical low-profile compact W/E adjustable green laser. Inanother embodiment, the mode of the sight 100 is switchable fromconstant to pulse, and vice versa. In another embodiment, the switch 120can be pushed to be ON or OFF. It is important to note that a furtherembodiment, the momentary sensor 121 can be easily controlled especiallyfor silent and quick operation. In still a further embodiment, thecharging socket 160 has a built-in rechargeable battery compatible withUSB Type-C charger.

The sight 100 can be attached to a firearm as shown in FIG. 3. The usercan first loosen the locking screws 140 of the sight 100, push/hold thelocking screws 140, align the locking screws 140 with the groove of therail of the firearm, clamp the sight onto the rail of the firearm, andtighten the locking screw 140 to complete the mounting process.

When in use, the user can press the switch 120 to turn on the sight 100.The momentary sensor 121 is configured to periodically emit a testinglight with a predetermined frequency and detect the strength of areflexed testing light to determine whether to shut off the laser beams.In one embodiment, the momentary sensor 121 can emit infrared light andif the infrared light is deflected by the user's finger to cause thechange of the strength of the reflexed infrared light, the laser beamemitted from the laser sight 130 will be turned off. So, if the userwants to turn off the laser beam, the user can simply move the fingertoward the momentary sensor 121 to somewhat covers the momentary sensor121 to deflect the infrared light emitting therefrom. In one use case,when the firearm with the sight 100 is disposed into a gun bag, themomentary sensor 121 can still be triggered to turn off the laser beam.

It is noted that the momentary sensor 121 is configured to temporarilyshut off the laser beam. Namely, when the user moves the finger awayfrom the momentary sensor 121, the infrared light emitting therefrom isnot deflected and the laser beam from the laser sight 130 can again beturned on. It is also noted that the switch has to be “ON” to triggerthe momentary sensor 121.

In a further embodiment, the sight can be charged through the chargingsocket 160. More specifically, as shown in FIG. 4, one end of a USBcharging cable can be plugged into the charging socket 160 on the sight100 and the other end can be connected to a USB power adapter tocomplete the charging process.
